BINDER ATYTACHMENT FOR HARVESTERS.

SPECIFICATION forming-part of Letters Patent No. 280,619, dated July3,1883,

' Application filed September 23, 1882. (No model.)

l To all whom,- Lt may concern:

Be it known that I, MASON HEDRICK, a resident of Oakland City, in thecounty of Gibson and State of Indiana, have invented a new and usefulImprovement in Binderl Attachments for Harvesters, of which thefollowing is a specification, having reference to the accompanyingdrawings. a

This-invention is an improvement on a de- Io vice for a like purpose forwhich Letters Patent of the 'United States No. 250,915 were granted tome December 13, 1881; and it relates to improved attachments toharvesters by the aid of which one man riding in a seat secured to thebinder-frame can bind grain as fast as a harvester can cut it.

My invention consists in an improved mechanism for automatically gagingthe size of the gavels and delivering them when formed to 2o thecompressing-arms for binding.

It also consists in an improved mechanism for controlling the movementof the arms for compressing the gavel to receive the band, all ashereinafter more fully set forth, and particu- 2 5 larly pointed out inthe claims.

Figure l is a side elevation, showing my improvements mounted in placeon the frame of a harvester. Fig. 2 is a partial end View, showing themechanism for operating and con- 3o trolling the arms for lcompressingthe gavel ready for binding. Fig. 3 is a vertical section through as w,Fig. l, shovfing the mechanism for forming the grain into gavels and fordelivering the same to thecompressing-arms.

Like letters refer to the same parts in all gures.

A represents the elevator of usual form, by means of which the cut grainis elevated from the platform of the harvester and delivered on 4o thesloping curved apron b, down which it passes by force of gravity aidedby the elastic radial arms c c on the wheels d d, which arms alsooperate to straighten the straw, feed it to the packer, and prevent itsrebounding from 4 5 the packers as it moves forward. For the purpose ofmaking the action of the arms c c more yielding and elastic thanr itwould be if said arms were rigidly secured to the periphery of wheels dd, I attach said arms to an 5o elastic band which closely fits theperiphery of said wheels. The wheels (l d are mounted on a shaft, whichis caused to revolve by a snitable connection with the driving mechanismof the elevator.

B B are vibrating packing-arms secured to a rocking-shaft, e, whichshaft is rocked bythe rod f, connecting the arm f on said rockshaft witha crank-wheel, (not shown,) which receives its motion from the beltdriving the elevator. The upper ends of the arms B B 6o project throughslots -in the apron b, and are made wide, so as to prevent the grainfrom falling behind them. The outward and downward movement of the grainis arrested by one ofthe radial arms g g2 g, which arms are 65 connectedto a central hub secured to a short shaft, h, which is mounted insuitable bearings on the frame, as shown. One of said arms is maintainedin an upright position across the opening of the chute formed by theapron b 7o and top covering, i, by means of a stop, k, secured to theshaft lz, and having flat edges corresponding in number with the radialarms, and a fiat spring, j, which rests against one side of the stop k'.The top covering, i, is of 75 sheet metal, and fills the space betweenthe ends of the frame except where slotted for the -passage of theradial arms of the wheels d d.

A .triangular plate, Z, is also secured to the shaft 7L, for a purposehereinafter explained. 8o A reciprocating bar, m, slotted at n, andresting on the shaft h, which passes through said slot, is given areciprocating motion by means of an arm, o, to which one end of said baris attached, the armo being secured to and vibrated by lthe rock-shafte. A projecting lug, p, is secured to the bar m in such a position as topass freely fover the edge of the plate Z, when said plate is in itsnormal position, but when the corner of said plate is raised by the 9opartial rotation of the shaft 7L, to which it is secured, said corner isengaged by the lug'p at its next outward movement, and the shaft 71 withits arms, is caused to make one-third of a revolution, as hereinaftermore fully ex- 9 5 plained. The slot u is made somewhat wider than thediameter ofthe shaft 71., upon which it moves, for the purpose ofallowing the lug p to ride over the corner of the plate Z, when saidcorner is raised during the inward stroke of 10o lthe bar m.

Narrow, flat, curved guides 1' o' are secured at one end to the frame ofthe binder, and the other ends, hanging free, serve to guide and holdthe grain down as it .is

closed.

pressed against the arm g by the paeki ng-arms B B, and also to guidethe gavel when it is discharged into Jthe compressor.

C represents the arms for compressing and holding the gavel during theprocess ol' tying the band. These arc made and operated in a mannersimilar to that described in my before mentioned Letters Patent, exceptthat I have provided a new means ol` giving motion to the rock-shalt andarms, by which said arms are In my l'ormer device motion was imparted tosaid shaft by means of a belt passing from the driving mechanism arounda pulley on said shaft, and the arms were held in position, when closed,by means ol' the l'orward movement ot' the belt alone. ln this case thesame shaft S is partially rotated and the arms C closed by means ol' anarm, 1, Figs. il and 2, which receives a continuous vibratory motionfrom the complete revolution of the crank u, attached to shaft fr, whichis driven by the driving-wheel ol` the harvesterthrough a pair ol`bevel-gears, or in any other suitable manner. The arm and crank a areconnected bythe pitmau ze. y[The arm i moves loosely on the shal't S,and the sha t't is caused to partiall y revolve by the clutch y, made toengage with the arm I by means ol' the treadle .2', rod 2, and lever 23.A short arm, i., is secured to the shalt S, its end being adapted toengage the ratchetlever 5. A spiral spring, (5, is coiled about andattached to the shaft S in such a manner that when the arms (l areclosed said spring is put in tension, and by its recoil will act to opensaid arms. Movement is communicated from thc shaflt to the arms C bymeans o'l'the arms N and li and eonnecting-rods M and Q, as in myprevious patent.

The operation ol' my device is as l'ollows: The grain being deliveredupon the apron b by the elevator A, it slides down and is pushed outwardand straightened by the arms c, until it is caught and carried onward bythe vibrating arms B ll, which push it against the vertical arm y. lt isheld down somewhat by the guides r r until a gavel has been formed.\Vhen the pressure againstihe arm y becomes so great as to partiallyovercome the tension ol the spring j, the arm f/ is pushed by saidpressure slightly outward, thus partially rotating the shalt l1, towhich it is secured, and the corner ol the plate I is thereby raisedinto the path of thc lug j) on the reciprocatingbar l111/, which,engaging the plate as it moves outward, l'urther rotates the shalt l1,and the next succeeding arm y comes up behind the gavel, separating itfrom the unpacked straw, and, as it rises to a vertical position, throwsthe gavel into the co1upressing-arms C. At this moment the operator, whois carried by a seat secured to the frame of the harvester withinconvenient reach ol' the compressing-arms, places his l'oot upon thetreadle c, which, opcrating the lever 3, causes the clutch y to engagewith the vibrating arm by means ot' which the shalt S is partiallyrotated and the arms C closed, the band having been previously laid inthem, thus compressing the gavel and carrying the band around it. Thearm 4: now engages theratehet-lever 5, and the gavel is held while theband is tied bythe operator. The arm 4L is so arranged in relation tothe arm tthat it engages and held by the ratchetlever when the arm t hasreached its extreme outward movement. As the arm t returns it simplyslips back over the clutch y. When the band is tied, the operatorremoves his foot from the treadle, and the clutch v/ is returned to itsnormal position by a liat spring, 7. The treadle, being also drawnupward by the action ol' said spring, raises the long arm of theratchet-lever 5, which rests upon it, thereby releasing the arm Ll, andthe shalt S is rotated backward bythe recoil ot' the spring t5, the armsC are thrown open, and the operator removes the sheal'.
